Cris:
---This is the code of the following series of short tutorials - listed bellow later.
The code was written in 2021. In the meantime "gym" environments
was "moved" to gymnasium and old code must be updated to work.
I made changes in Notebooks to make the code work in 2025 - inspired by A.Geron's book code.
---/src/*.py programs were changed too.
---Pau Labarta Bajo did a great job with these mini-tutorials and his coding style.
You should read the tutorials while runing the JUpyter Notebooks yourself!
